Let is the focal length of glass convex lens and be the focal length of liquid lens. The focal length of the combination of two lenses can be taken as F.
Then,
The liquid lens formed is a planoconcave lens.
According to lens maker’s formula
Since the liquid lens is planoconcave, = R and = ∞
So, the equation becomes
Refractive index n= 1+
